Preliminary Datasheet
150mA RF ULDO REGULATOR
AP2202
General Description
Features
The AP2202 is a 150mA ULDO regulator which provides 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 applications, such as RF electronics.

The AP2202 also features logic compatible enable/
shutdown control inputs, a low power shutdown mode
for extended battery life, over current protection, over
temperature protection, as well as reversed-battery protection.
The output capacitor of 1.0µF minimum and 2.2µF
minimum near its pin are recommended when CBYP is
unused and 470pF respectively. Tantalum or aluminium electrolytic capacitors are adequate. Bypass
capacitor is connected to the internal voltage reference
to quiet noise. Its recommended value is from 470pF to
1nF. If output noise is not a major concern and rapid
turn-on is necessary, omit CBYP and leave BYP open.

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 allowable 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 temperature, 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.

Figure 15. Typical Application of AP2202
Application Information
In most cases, tantalum or aluminium electrolytic
capacitors are adequate.
External Capacitors
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
CBYP, output capacitors of 2.2µF or greater are
required for better stability.
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.
Output Capacitor
It is required to prevent oscillation. 1.0µF minimum
is recommended when CBYP is unused. 2.2µF minimum is recommended when CBYP is 470pF. The output capacitor may be increased without limit for
large values to improve transient response.
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
CBYP and leave BYP open.
