CL432S Datasheet

1.25vprecision Adjustable Shunt Reference / Amplifier


Features, Applications

Temperature-Compensated: 50ppm/ C Trimmed 0.5% Bandgap Reference Internal Amplifier with 150mA Capability Nominal Temperature Range Extended to 105oC Low Frequency Dynamic Output Impedance: < 150m Low Output Noise

Calogic's a 3-terminal Adjustable Shunt Regulator highly accurate 1.25V bandgap reference with a 0.5% tolerance. The device offers thermal stability, wide operating current (100mA) and an extended temperature range to 105oC for operation in power supply applications. The CL432 offers a wide operating voltage range to 18V and is an excellent choice for voltage reference requirements in an isolated feedback circuit for to 3.3V switching mode power supplies. The tight tolerance guarantees a lower design cost for the power supply manufacturer by virtually eliminating the need for an extra power supply manufacturing process of the power supply. The device is housed in several package options to meet the designers criteria. ORDERING INFORMATION Part CL432VS CL432S Package TO-92 8-Pin Plastic SOIC SOT-23 SOT-89 Temperature Range to 105oC
