AP2120N-1.2TRG1

AP2120 HIGH SPEED, EXTREMELY LOW NOISE LDO REGULATOR Description Pin Assignments 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, and a current limit circuit for current protection. (Top View) VIN 3 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. • 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 • • • • GND VOUT Applications Features • • • 2 SOT-23 (N Package) The AP2120 are available in standard SOT-23 packages. • • • • 1 • • • • • • Mobile Phones, Cordless Phones Wireless Communication Equipment Portable Games Cameras, Video Recorders Sub-Board Power Supplies for Telecom Equipment Battery Powered Equipment 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) Moisture Sensitivity: Level 1 per J-STD-020 Terminals: Finish - Mate Tin Plated Leads, Solderable per MILSTD-202, Method 208 Weight: 0.009 grams (Approximate) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ Notes: AP2120 1.
