RP104N121B集成电路（IC）的线性+开关稳压器规格书PDF中文资料

OUTLINE

The RP104x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current and low ON-resistance. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit and a chip enable circuit.

These ICs perform with ultra low supply current (Typ.1.0µA), which prolong the battery life.

Since the packages for these ICs are PLP1010-4, SOT-23-5 and SC-82AB, therefore high density mounting of the ICs on boards is possible.
