LA5601
Low Saturation Regulator with Reset
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.

Sample Application Circuit 1
Note ) 1. Capacitors Cn and CRES are only required if problems are experienced with noise from external sources. 2. If capacitor Cn is present, ensure that Co is at least more than one-third of the value of Cin in order to prevent output noise at power-down due to capacitor discharge timing. 3. The minimum recommended value of output capacitor Co is 47F. 4. Use low temperature coefficient capacitor for the delay time capacitor Cd. No.3222-3/8

Sample Application Circuit 2 (Delay start regulator)
Sample Application Circuit 3 (Positive-to-negative DC converter)
Note ) 1. The output voltage can be fine-trimmed by adjusting R1. To protect the output transistor against overvoltage, ensure that either R1 is non zero or use a low-Q coil for L1. 2. A load must always be present on power-up. To safeguard against excessive output voltages that occur when the circuit is powered up without a load, a dummy load resistor is recommended. This is shown on the circuit as R2. 3. Select VIN, R1 and L1 so that VOD<14V, and IODL<120mA. The component values shown reguire that VIN never exceeds 9V.
