The ISL97536 is a synchronous, integrated FET 1A step-down regulator with internal compensation. It operates with an input voltage range from 2. 5V to 6V, which accommodates supplies of 3. 3V, 5V, or a Li-ion battery source. The output can be externally set from 0. 8V to VIN with a resistive divider. The ISL97536 features PWM control with a 1. 4MHz typical switching frequency. The typical no load quiescent current is only 500µA. Additional features include a 100ms Power-On- Reset output, 2 of PCB area with components on one side only. The 10 Ld MSOP package is specified for operation over the full -40°C to +85°C temperature range.
