Monolithic 1A Step-Down Regulator with
Low Quiescent Current
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 V
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, <1µA shutdown current, short-circuit
protection, and over-temperature protection.
The ISL97536 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.15in
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.

Component Selection Because of the fixed internal compensation, the component choice is relatively narrow. For a regulator with fixed output voltage, only two capacitors and one inductor are required. Capacitors must be chosen in the range of 10µF to 40µF, ...
