1 / 3 page HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : Preliminary Data Issued Date : 1998.08.01 Revised Date : 2000.10.01 Page No. : 1/3 HSMC Product Specification H7805AI H7805BI 3-TERMINAL POSITIVE VOLTAGE REGULATOR Description The H7805_I series of three-terminal positive regulators are available in the TO-251 package and with several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe operating area protection, making it essent-ially 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. H7805_I is characterized for operation from 0 °C to +125°C, and if operating temperature will al- ways hi, please refer the power dissipation curve. Absolute Maximum Ratings (Ta=25 °C) • Input Voltage......................................................................... 35 V (5V Through 9V), 40 V (24V) • Total Power Dissipation ........................................................................................... Internal limit • Operating Temperature Range ............................................................................ 0 °C to +70 °C • Maximum Junction Temperature...................................................................................... 125 °C • Storage Temperature Range .......................................................................... -55 °C to +150 °C • Lead Temperature (Soldering 10S).................................................................................. 230 °C Typical Application Schematic Diagram 6.3V 3.4K 200 10K 200 1K 2K 0.3 26 4K 20pF 4K 1K 12.1K 1.2 26 1.9K 30K VREF Input Output GND H7805_I Vout Vin 3 1 2 C1 C2 Note : C1 and C2 are required if regulator is located far from power supply filter and load, or oscillation may induced on the loop. |
