RP152x Series 150 mA Low Voltage Dual-Channel LDO Regulator with Sequence Control NO.EA-200-160707 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 6pi- n SOT-23-6 package and a 6pi- n DFN1212-6 package. Both packages are equipped with two LDOs which can achieve high-density mounting.

Selection Guide Package Quantity per Reel Pb Free Halogen Free Product Name RP152Lxxx-TR DFN1212-6 5,000 pcs Yes Yes RP152Nxxx-TR-FE SOT-23-6 3,000 pcs Yes Yes xxx: Specify the combination of set output voltage (V ) within the range of 0.8 V to 3.6 V in 0.1 V step. SET : Specify the auto-discharge function and the start-up sequence control. (A) Auto-discharge function not included (B) Auto-discharge function included (C) Start-up sequence control and Auto-discharge function included 1 Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the external capacitor when the chip enable signal is switched from the active mode to the standby mode. 2
