Datasheet Analog Devices ADP5023ACPZ-R2 — 数据表

Dual 3 MHz, 800 mA Buck
Regulators with One 300 mA LDO
ADP5023 Data Sheet above a predefined threshold. When the load current falls below
a predefined threshold, the regulator operates in power save
mode (PSM) improving the light-load efficiency. FEATURES
Main input voltage range: 2.3 V to 5.5 V
Two 800 mA buck regulators and one 300 mA LDO
24-lead, 4 mm × 4 mm LFCSP package
Regulator accuracy: ±1.8%
Factory programmable or external adjustable VOUTx
3 MHz buck operation with forced PWM and auto PWM/PSM
modes
BUCK1/BUCK2: output voltage range from 0.8 V to 3.8 V
