1. Description

ADP7104ARDZ-5.0-R7 is a CMOS low-dropout linear regulator with an operating voltage range of 3.3 V to 20 V and an output up to 500 mA current. This high input voltage LDO is very suitable for regulation High-performance analog and mixed-signal circuit operation 19 V to 1.22 V power rail. Using an advanced proprietary architecture, it provides high power supply rejection, low noise and Achieve excellent line and load transient response Small 1 μF ceramic output capacitor. ADP7104 provides seven fixed output voltage options And adjustable version, allowable output voltage range From 1.22 V to VIN − VDO through an external feedback voltage divider. The ADP7104 output noise voltage is 15 μV rms, independent of the output voltage. Good digital power output Allow the power system monitor to check the health of the output Voltage. User programmable precision undervoltage lockout Function helps to sequence multiple power supplies. The ADP7104 is available in an 8-lead, 3 mm × 3 mm LFCSP package And 8-pin SOIC package. LFCSP provides a very compact Solution and provide excellent thermal performance Applications requiring up to 500 mA output current Small, low-key footprint.
