1.0A LOW DROPOUT PRECISION LINEAR REGULATORS
Features
Description
Adjustable or Fixed Output
GM1117 of positive adjustable and fixed regulators is de-
signed to provide 1.0A output with low dropout voltage per-
formance. On-chip trimming adjusts the reference voltage
to 1%. For usage on working in post regulators or micro-
processor power supplies, low voltage operation and fast
transient response are required.
Output Current of 1.0A
Dropout Voltage (Typical) 1.15V @ 1.0A
Line Regulation 0.2% max.
Load Regulation 0.4% max.
Fast Transient Response
Pin-to-pin compatible with the LT1086 family of regulators,
GM1117 is available in surface-mount SOT-223 and TO-
252 packages.

GM1117 linear regulators provide fixed and adjustable
output voltages at currents up to 1.0A. These regula-
tors are protected against overcurrent conditions and in-
clude thermal shutdown protection. The GM1117's
have a composite PNP-NPN output transistor and re-
quire an output capacitor for stability. A detailed proce-
dure for selecting this capacitor follows.

Stability Considerations
Adjustable Operation
The output compensation capacitor helps to deter-
mine three main characteristics of a linear regula-
tor's performance: start-up delay, load transient re-
sponse, and loop stability. The capacitor value and
type is based on cost, availability, size and tempera-
ture constraints. A tantalum or aluminum electrolytic
capacitor is preferred, as a film or ceramic capacitor
with almost zero ESR can cause instability. An alu-
minum electrolytic capacitor is the least expensive
type, but when the circuit operates at low tempera-
tures, both the value and ESR of the capacitor will
vary widely. For optimum performance over the full
operating temperature range, a tantalum capacitor is
best. A 22µF tantalum capacitor will work fine in
most applications, but with high current regulators
such as the GM1117 higher capacitance values will
improve the transient response and stability. Most ap-
plications for the GM1117's involve large changes in
load current, so the output capacitor must supply in-
stantaneous load current. The ESR of the output ca-
pacitor causes an immediate drop in output voltage
The GM1117 has an output voltage range of 1.25 V to
5.5 V. An external resistor divider sets the output volt-
age as shown in Figure 1. The regulator maintains a
fixed 1.25V (typical) reference between the output pin
and the adjust pin.
A resistor divider network R1 and R2 causes a
fixed current to flow to ground. This current
creates a voltage across R2 that adds to the 1.25 V
across R1 and sets the overall output voltage. The
adjust pin current (typically 50 µA) also flows
through R2 and adds a small error that should be
taken into account if precise adjustment of V
is

necessary.
The output voltage is set according to the formula:
R1 + R2
V
= V
X (
) + I
X R2
OUT
REF
Adj
R1
The term IAdj × R2 represents the error added by the
adjust pin current.
R1 is chosen so that the minimum load current is at
least 2.0 mA. R1 and R2 should be the same type,
e.g. metal film for best tracking over temperature.
While not required, a bypass capacitor from the
adjust pin to ground will improve ripple rejection
given by:
DV = DI x ESR
In microprocessor applications an output capacitor
network of several tantalum and ceramic capacitors
in parallel is commonly used. This reduces overall
ESR and minimizes the instantaneous output volt-
age drop under transient load conditions. The output
capacitor network should be placed as close to the
load as possible for the best results.
and transient response.
A 0.1 µF tantalum
capacitor is recommended for “first cut” design.
Type and value may be varied to obtain optimum
performance vs. price.
Used with large output capacitance values and the
input voltage is instantaneously shorted to ground,
damage can occur. In this case, a diode connected
as shown above in Figure 1.

Protection Diodes
Output Voltage Sensing
When large external capacitors are used with most
linear regulator, it is wise to add protection diodes. If
the input voltage of the regulator is shorted, the out-
put capacitor will discharge into the output of the reg-
ulator. The discharge current depends on the value
The GM1117 are three terminal regulators. For which,
they cannot provide true remote load sensing. Load
regulation is limited by the resistance of the conductors
connecting the regulator to the load. For best results

The GM1117 precision linear regulators include thermal
shutdown and current limit circuitry to protect the de-
vices. However, high power regulators normally oper-
ate at high junction temperatures. It is important to cal-
culate the power dissipation and junction temperatures
accurately to be sure that you use and adequate heat
In the GM1117 linear regulators, the discharge path
is through a large junction, and protection diodes are
normally not needed. However, damage can occur if
the regulator is used with large output capacitance
values and the input voltage is instantaneously
shorted to ground. In this case, a diode connected

A heat sink effectively increases the surface area of
the package to improve the flow of heat away from
