1 / 8 page  SmartSwitch™ General Description The AHK432 is a low voltage adjustable shunt refer- ence with thermal stability guaranteed over the full industrial temperature range. This 3-terminal regula- tor has an output voltage range that extends from VREF (1.24V) to 20V, giving designers outstanding flexibility in the development of power supplies and instrumentation. With a low operating current of 60µA, the AHK432 is well suited for battery-powered portable electronic applications. It also has a sharp turn-on characteristic and a dynamic resistance of only 50mW making it an excellent replacement for zener diodes in low tempco designs. The AHK432 is available in the surface-mount 3 or 5 pin SOT-23, as well as the through hole TO-92. Three voltage tolerance options are offered in each package: ±0.5%, ±1%, and ±2%. Features • Wide output voltage range (1.24 to 20V) • Operating current from 60µA to 100mA • Low dynamic output resistance of 50m Ω • ±0.5% trimmed voltage reference • 10mV typ. VREF deviation, from -40 to +105°C • Surface mount 3 or 5 pin SOT-23 or through- hole 3 pin TO-92 packages Applications • Notebook computers • Isolated feedback in switching power supplies • Adjustable and programmable supplies • Linear regulators (External Reference) • Instrumentation • Medical Electronics* • Global voltage reference for multiple power supplies AHK432 Adjustable Low Voltage Shunt Regulator 432.2001.11.0.96 1 Typical Application RL IN OUT R2 R1 AHK432 Adjustable regulator: OUT = VREF R1 + R2 R2 PowerManager™ |
