Description

The EL7534 is a synchronous, integrated FET 600mA 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 Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider.

The EL7534 features PWM mode control. The operating frequency is typically 1.5MHz. Additional features include a 100ms Power-On-Reset output, <1µA shut-down current, short-circuit protection, and over-temperature protection.

The EL7534 is available in the 10-pin MSOP package, making the entire converter occupy less than 0.15 in² of PCB area with components on one side only. Both packages are specified for operation over the full -40°C to +85°C temperature range.
