AP2120
HIGH SPEED, EXTREMELY LOW NOISE LDO REGULATOR
Description
The AP2120 series are positive voltage regulator ICs fabricated by
CMOS process. Each of these ICs consists of a voltage reference, an
error amplifier, a resistor network for setting output voltage, a current
limit circuit for current protection.
The AP2120 series feature high supply voltage ripple rejection, low
dropout voltage, low noise, high output voltage accuracy, and low
current consumption which make them ideal for use in various
battery-powered devices.
The AP2120 series have 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V,
3.2V, 3.3V, 3.6V, 4.0V and 5.0V versions.
The AP2120 are available in standard SOT-23 and TO-92 packages.
Features
Low Dropout Voltage at IOUT = 100mA: 200mV Typical (Except
1.2V, 1.3V and 1.5V Versions)
Low Quiescent Current: 25µA Typical
High Ripple Rejection: 65dB Typical (f = 1kHz)
Output Current: More Than 150mA (250mA Limit)
Extremely Low Noise: 15µVrms@VOUT = 1.2V, 1.3V, 1.5V (10Hz
to 100kHz)
Excellent Line Regulation: 4mV Typical
Excellent Load Regulation: 12mV Typical
High Output Voltage Accuracy: ±2%
Excellent Line Transient Response and Load Transient
Response
Compatible with Low ESR Ceramic Capacitor (as Low as 1µF)
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Applications

Note: Filter capacitors are required at the AP2120's input and output. 1µF capacitor is required at the input. The minimum output capacitance required for stability
should be more than 1µF with ESR from 0.01Ω to 100Ω. Ceramic capacitors are recommended.

Notes: 4. Stresses greater than those listed under “Absolute Maximum Ratings can 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 can affect device reliability.
5. Absolute maximum ratings indicate limits beyond which damage to the component can occur. 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.
