MITSUBISHI <Dig./Ana. INTERFACE> M5S237L,ML 3-TERMINAL ADJUSTABLE REGULATOR

DESCRIPTION

The M6237 is a semiconductor integrated circuit which is PIN CONFIGURATION designed for variable output voltage regulator and is low power dissipation type with input-output voltage difference are quite low. Fa Housed in its 3-pin package are Reference voltage 8 generator circuit, Differential amplifier and Drive circuit. r FEATURES [| Js| © Wide operating supply voltage range. Vin = 3.5V ~ 36V. Vo = 1.5V ~ 33V . © The input-output voltage differences can be small moved Outline SOT-89(ML) by the external PNP transistors. (Tr: Vee(ear state) Od® Vi-o(min) = 0.2V @ The output voltage can be freely adjusted by the external Outline TO-92L(L) resistors. © Built in Over-current protection circuit (Drooping fold-back ELECTRODE CONNECTIONS unit), ASO protection circuit and Thermal protection © 1NpuT circuit. @ GROUND © Its possible Taping (Automatic insert) and Lead forming. @ ouTPur APPLICATION Car stereos, radio cassettes, portable stereos, and other general usage electronic power supplies RECOMMENDED OPERATING CONDITIONS Bl K DIAGRAI LOCK D 5 M ah 9 OUTPUT (wo) M5237 Wo) <O) Vin Ro
