| HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : HJ200210 Issued Date : 1998.08.01 Revised Date : 2002.08.09 Page No. : 1/3 H7812AJ H7812BJ 3-TERMINAL POSITIVE VOLTAGE REGULATOR Description TO-252 The H7812_J series of three-terminal positive regulators are available in the TO-252 package. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each employs internal current limiting, thermal shut-down and safe operating area protection, making it essen-tially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. H7812_J is characterized for operation from 0C to +125C, and if operating temperature is always high, please refer to the power dissipation curve.
