RS7202

250mA Low Quiescent Linear Regulator with Enable

General Description

The RS7202 series is a positive voltage regulator with high accuracy output voltage and ultra‐low quiescent current which is

typically 2.0μA. The device is ideal for handheld communication equipments and battery powered applications which

require low quiescent current.

The RS7202 consists of a bandgap reference voltage source, an error amplifier, a P‐channel pass transistor, a resistor‐

divider for setting output voltage, a current limiter, and temperature limit protection circuit. The high‐accuracy output

voltage is preset at an internally trimmed voltage 1.8V, 2.5V or 3.3V. Other output voltages can be mask‐ optioned from

1.2V to 5.0V with 100mV increment except the RS7202‐13 which has 1.3V output voltage and RS7202‐185 which has 1.85V

output voltage.

The RS7202 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of

1.0μF. The device is available in SOT‐25 package.
