300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR
General Description
Features
AP2125
The AP2125 series are 300mA, positive voltage regu-
lator ICs fabricated by CMOS process.
Each of these ICs is equipped with a voltage reference,
an error amplifier, a resistor network for setting output
voltage, a chip enable circuit, a current limit circuit and
OTSD (over temperature shut down) circuit to prevent
the IC from over current and over temperature.
The AP2125 series have features of high ripple rejec-
tion, low dropout voltage, low noise, high output volt-
age accuracy and low current consumption which
make them ideal for use in various battery-powered
apparatus.
· Excellent Ripple Rejection: 70dB Typical (1.8V
Version)
· Low Dropout Voltage: 65mV (IOUT=100mA,
3.3V Version)
· Low Standby Current: 0.01µA Typical
· Low Quiescent Current: 60µA Typical
· Extremely Low Noise: 50µVrms Typical
· Maximum Output Current: 300mA (Min.)
· High Output Voltage Accuracy: ±2%
· Compatible with Low ESR Ceramic Capacitor
· Excellent Line/Load Regulation
Applications
The AP2125 have 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.15V
and 4.2V fixed voltage versions.
· CDMA/GSM Cellular Handsets
· Battery-powered Equipments
These ICs are available in tiny SC-70-5 and SC-82 · Laptops, Palmtops, Notebook Computers
packages as well as industry standard SOT-23-3 and · Hand-held Instruments
SOT-23-5 packages.
· PCMCIA Cards
· Portable Information Appliances
