OUTLINE

The RP153L 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 RP153L consists of a voltage reference

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

The RP153L is available in fixed output voltage options. Besides the low supply current by CMOS, the RP153L

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 RP153L is further improved in ripple

rejection, line transient response, and load transient response. All these features allow the RP153L to become

ideal power sources for hand-held communication equipment.

The RP153L is offered in an 8-pin DFN1216-8 package which can achieve high-density mounting.
