AP7313 150mA, Low Quiescent Current, Fast Transient Low Dropout Linear Regulator Features Description The AP7313 is a 150mA, fixed output voltage, low dropout linear 150mA Low Dropout Regulator in 3-pin package regulator. The device included pass element, error amplifier, Very low I over full load: 65A Q band-gap, current limit and thermal shutdown circuitry. Wide input voltage range: 2V to 6V Fixed output options: 1.0V to 3.3V The characteristics of low dropout voltage and low quiescent PSRR: 65dB at 100Hz current make it suitable for low power applications, for example, battery powered devices. The typical quiescent current is Fast start-up time: 80s approximately 65 A. Stable with low ESR, 1F ceramic output capacitor Excellent Load/Line Transient Response Built-in current-limit and thermal-shutdown functions prevent IC Low dropout: 150mV typical at 150mA from damage in fault conditions. Current limit protection The AP7313 is available in SOT23 package with different Short circuit protection pin-outs. Thermal shutdown protection Ambient temperature range: -40C to 85C SOT23 and SOT23R: Available in Green Molding Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (Note 1) Applications Notebook and Desktop Computers and Pheripherals Portable Devices Battery Powered Devices CD-ROM, DVD and LAN Cards Typical Application Circuit V V OUT IN IN OUT AP7313 1uF 1uF GND AP7313 Rev. 2 1 of 13 NOVEMBER 2009 www.diodes.com Diodes Incorporated AP7313 150mA, Low Quiescent Current, Fast Transient Low Dropout Linear Regulator Ordering Information AP7313 - XX XX G - 7 Output Packing Package Green 10 : 1.0V SA : SOT23 G : Green 7 : Tape & Reel 12 : 1.2V SR : SOT23R 15 : 1.5V 18 : 1.8V 20 : 2.0V 25 : 2.5V 28 : 2.8V 30 : 3.0V 33 : 3.3V Packaging 7 Tape and Reel Device Package Code (Note 2) Quantity Part Number Suffix AP7313-XXSAG-7 SA SOT23 3000/Tape & Reel -7 AP7313-XXSRG-7 SR SOT23R 3000/Tape & Reel -7 Notes: 1.
