ADI ADP7105ARDZ-1.8

正20V500mA

Overview

The ADP7105ARDZ-1.8-R7 is a CMOS, low dropout (LDO) linear regulator that operates from 3.3 V to 20 V and provides up to 500 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed-signal circuits operating from 1.22 V to 19 V rails. Using an advanced proprietary architecture, the ADP7105ARDZ-1.8-R7 provides high power supply rejection and low noise, and achieves excellent line and load transient response with only a small 1 μF ceramic output capacitor.

   Input voltage range: 3.3 V to 20 V   Maximum output current: 500 mA   Low noise: 15 μV rms for fixed output versions   PSRR performance of 60 dB at 10 kHz, VOUT = 3.3 V   Reverse current protection   Low dropout voltage: 350 mV at 500 mA   Initial accuracy: ±0.8%   Accuracy over line, load, and temperature      2% to +1%, TJ = 40℃ to +125℃      1.25% to +1%, TJ = 0℃ to +85℃   Low quiescent current: 900 μA at VIN = 10 V, IOUT = 500 mA   Low shutdown current: <50 μA at VIN = 12 V, stable with      small 1 μF ceramic output capacitor   3 fixed output voltage options: 1.8, 3.3 V and 5 V   Adjustable output from 1.22 V to 19 V   Programmable soft start for inrush current control   Foldback current-limit and thermal overload protection   User programmable precision UVLO/enable   Power-good indicator   8-lead LFCSP and 8-lead SOIC packages
