RP152

RP152/153 Series PRELIMINARY 150mA Dual LDO REGULATOR OUTLINE NO.EA-200-20090311 The RP152/153x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting Output Voltage, a current limit circuit, and a chip enable circuit. Moreover, in C Version of RP152, the start-up sequence circuit is built-in. These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip enable function prolongs the battery life of each system. The line transient response and load transient response of the RP152/153x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are SOT-23-6 and DFN1212-6 for RP152, and DFN1216-8 for RP153, dual LDO regulators are included in each package are high density mounting of the ICs on boards is possible. In RP153, the power supply of each circuit can be individually supplied. The transient response characteristic of D and E Version is improved. (The supply current: Typ. 85μA).
