Overview
The LA5601 is a voltage regulator with a low-voltage detector and reset controller for use in microprocessor-based systems. It generates a reset signal for low power supply voltage. It also features a low 0.25V (typ.) saturation voltage for reduced power dissipation and power supply size. Applications include microprocessor-controlled consumer electronic equipment such as CD players, tuners and receivers, and preamplifiers.

FEATUREs
• Low minimum input-output voltage difference (0.3V typ).
• Supports setting of reset output delay time using external capacitor.
• Built-in fold-back current limiting circuit and excessive heat protection circuit.
• Reset output using active pull-up for simpler noise reduction and use with internal pull-down logic circuits.
• Error amplifier noise filter pin.
• Auxiliary regulator with reverse current protection.

Functions
• Low saturation regulator with 250mA and 5.2V output.
• Power supply reset generator function.
• Supports on-off control of 5.2V using equipped enable pin (high active).
• Built-in Darlington driver (120mA).
• Built-in auxiliary regulator (5.2V, 250mA).
