1 / 27 page  300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR AP2125 Data Sheet 1 May. 2010 Rev. 1. 4 BCD Semiconductor Manufacturing Limited General Description 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. The AP2125 have 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.15V and 4.2V fixed voltage versions. These ICs are available in tiny SC-70-5 and SC-82 packages as well as industry standard SOT-23-3 and SOT-23-5 packages. Features · 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 · CDMA/GSM Cellular Handsets · Battery-powered Equipments · Laptops, Palmtops, Notebook Computers · Hand-held Instruments · PCMCIA Cards · Portable Information Appliances Figure 1.
