RP152x Series

150 mA Low Voltage Dual-Channel LDO Regulator with Sequence Control

NO.EA-200-160707

1

OUTLINE

The RP152x is a 150 mA dual-channel LDO regulator that provides high ripple rejection, low dropout voltage,

high output voltage accuracy, and low supply current. Internally, the RP152x consists of a voltage reference

unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, and a chip enable circuit.

Moreover, the RP152xxxxC consists of a start-up sequence circuit.

The RP152x is available in fixed output voltage options. Besides the low supply current by CMOS, the RP152x

offers a low dropout voltage by built-in low ON resistance Tr. as well as an extended battery life by a chip

enable function. Compared with the existing CMOS-based regulators, the RP152x is further improved in ripple

rejection, line transient response, and load transient response. All these features allow the RP152x to become

ideal power sources for hand-held communication equipment.

The RP152x is offered in a 6-pin SOT-23-6 package and a 6-pin DFN1212-6 package. Both packages are

equipped with two LDOs which can achieve high-density mounting.
