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, 2 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.
