General Description

Tri-Mode: +3.3 V, +5 V, Adjustable Micropower Linear Voltage Regulators ADM663A/ADM666A* FUNCTIONAL BLOCK DIAGRAMS VIN 0.5V 1.3V A1 C1 SENSE VOUT2 VOUT1 SHDN D E C O D E R R1 C2 VIN–50mV VSET C3 50mV R2 0.9V A2 VTC R3 GND ADM663A The ADM663A/ADM666A are precision linear voltage regulators featuring a maximum quiescent current of 9 µA.

They can be used to give a fixed +3.3 V or +5 V output with no additional external components or can be adjusted from 1.3 V to 16 V using two external resistors.

Fixed or adjustable operation is automatically selected via the VSET input.
