CAT102集成电路（IC）的监控器规格书PDF中文资料

DESCRIPTION

The CAT102 is a low-voltage reference and amplifier. Designed for the control loop of low-voltage power supplies, the reference voltage has been designed for 600mV. Over a junction temperature from -40°C to 105°C, the reference voltage is within 8mV of the nominal 600mV. In addition, the error amplifier output and the supply voltage pin (IN) are on separate pins.
