TC59

Low Dropout, Negative Output Voltage Regulator

Features

General Description

• Low Dropout Voltage

The TC59 is a low dropout, negative output voltage

regulator designed specifically for battery-operated

systems. Its full CMOS construction eliminates the

wasted ground current typical of bipolar LDOs. This

reduced supply current significantly extends battery

life, particularly when the TC59 is operated in dropout.

- Typically 120mV @ 50mA; 380mV @ 100mA

for -5.0V Output Part

• Tight Output Voltage Tolerance: ±2% Max

• Low Supply Current: 3.5A, Typ

• Small Package: 3-Pin SOT-23A

Other TC59 key features include low supply current

(typically 3.0A) and low dropout operation (typically

120mV at 50mA). The TC59 is packaged in a small

3-Pin SOT-23A package.

DETAILED DESCRIPTION

A 1F input capacitor is recommended for most

applications when the input impedance is on the order

of 10. When operating off of a battery input, or there

is a large distance from the input source to the LDO,

larger input capacitance may be required for stability.

When large values of output capacitance are used, the

input capacitance should be increased to prevent high

source impedance oscillations.

The TC59 is a low quiescent current, precision fixed

negative output voltage LDO. Unlike bipolar linear

regulators, the TC59 supply current does not increase

proportionally with load current.

3.1

Output Capacitor

A minimum of 1F tantalum output capacitor is

required. The requirements for the output capacitor are

an equivalent series resistance (esr) greater than 0.1

and less than 5, with a self-resonant frequency

greater than 1MHz. To improve supply noise rejection

and transient response, larger output capacitors can be

used. Care should be taken when increasing C_OUT, that

the input impedance is not high enough to cause high

input impedance oscillation.

EQUATION 4-3:

P_TOTAL= P_D(Pass Device) + P_D(Bias)

4.1

THERMAL CONSIDERATIONS

Power Dissipation

The amount of power dissipated internal to the low drop

out linear regulator is the sum of the power dissipation

within the linear pass device (P-Channel MOSFET),

and the quiescent current required to bias the internal

reference and error amplifier. The internal linear pass

device power dissipation is calculated multiplying the

voltage across the linear device times the current

through the device. The input and output voltages are

negative for the TC59. The power dissipation is

calculated using the absolute value of the voltage

difference between the input and output voltage.

For the TC59, the internal quiescent bias current is so

low (3A typical), the P_D(Bias) term of the power

dissipation equation can be ignored. The maximum

power dissipation can be estimated by using the

maximum input voltage and the minimum output

voltage to obtain a maximum voltage differential

between input and output and multiplying the maximum

voltage differential by the maximum output current.

EQUATION 4-4:

P_MAX= (V_{IN (MAX)}– V_{OUT (MIN)}) X I_{OUT (MAX)}

EQUATION 4-1:

P_MAX

= (7V X (1.05) – (5.0V X 0.98)) X 40mA

= 98.0 milli-Watts

P_D(Pass Device) = (V_IN– V_OUT) X I_OUT

To determine the junction temperature of the device,

the thermal resistance from junction to air must be

known. The SOT-23-3 R_JAis estimated to be

approximately 359°C/W when mounted on a 4-layer

board. The R_JAwill vary with physical layout, airflow

and other application specific conditions.

The internal power dissipation as a result of the bias

current for the LDO internal reference and error

amplifier is calculated by multiplying the ground or

quiescent current times the input voltage.

EQUATION 4-2:

The device junction temperature is determined by

calculating the junction temperature rise above

ambient, then adding the rise to the ambient

temperature.

P_D(Bias) = V_INX I_GND

The total internal power dissipation is the sum of

Equation 4-1 and Equation 4-2.

NOTES:

DS21438C-page18

 2001-2012 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device

applications and the like is provided only for your convenience

and may be superseded by updates. It is your responsibility to

ensure that your application meets with your specifications.
