AN1432MS - Panasonic Semiconductor

AN1432MS low voltage operation shunt regulator

Pin No. 1 Symbol Reference Description Voltage Regulators The reference voltage (1.26 V typical) pin. Although the impedance is high under the normal using conditions, be careful that the impedance drops and current flows into the IC inside if a current or voltage is forced to apply from the outside. The pin for the combined use of the power source curren.
