EL7532 pdf datasheet (Monolith

Monolithic 2A Step-Down Regulator
The EL7532 is a synchronous, integrated FET 2A step-down
regulator with internal compensation. It operates with an
input voltage range from 2.5V to 5.5V, which accommodates
supplies of 3.3V, 5V, or a single Li-Ion battery source. The
output can be externally set from 0.8V to VIN with a resistive
divider.
The EL7532 features PWM mode control. The operating
frequency is typically 1.5MHz. Additional features include a
100ms Power-On-Reset output, <1μA shut-down current
and over-temperature protection.
The EL7532 is available in the 10-pin MSOP package,
making the entire converter occupy less than 0.18 in2 of
PCB area with components on one side only. The package is
specified for operation over the full -40°C to +85°C
temperature range.
