AP2202
General Description
Features
The AP2202 is a 150mA ULDO regulator which pro-
vides very low noise (45µVrms at 80Hz-100KHz),
ultra low dropout voltage (typically 165mV at
150mA), very low quiescent current (1µA maximum)
and excellent power supply ripple rejection (PSRR
75dB at 100Hz) in battery powered applications, such
as handsets and PDAs and in noise sensitive applica-
tions, such as RF electronics.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
Note 2: Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allow-
able power dissipation is a function of the maximum junction temperature, TJ(max), the junction-to-ambient thermal resistance,
θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated
using: PD(max)=(TJ(max) -TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die tempera-
ture, and the regulator will go into thermal shutdown.

Electrical Characteristics (Continued)
Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal
value measured at 1V differential.
Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.

Application Information
External Capacitors
In most cases, tantalum or aluminium electrolytic
capacitors are adequate.
Regarding good performance of regulator stability,
external capacitors required by the AP2202 should
be prudently selected.
Noise Bypass Capacitor
Bypass capacitor is connected to the internal voltage
reference. A 680pF capacitor connected from BYP to
GND leads reference to be quiet which results in a
significant reduction in output noise. When using
Input Capacitor
If there is more than 10 inches of wire between the
input and the AC filter, or if a battery is used as the
input, a 1µF capacitor should be placed from IN to
GND.
C
output capacitors of 2.2µF or greater are
BYP,
required for better stability.
Output Capacitor
It is required to prevent oscillation. 1.0µF minimum
is recommended when C
The start-up speed of the AP2202 is inversely
proportional to the value of reference bypass
capacitor. In some cases, if output noise is not a
major concern and rapid turn-on is necessary, omit
is unused. 2.2µF mini-

is 470pF. The out-
