CYStech Electronics Corp. 3-TERMINAL NEGATIVE VOLTAGE REGULATOR Spec. No. : C532E3 Issued Date : 2003.04.08 Revised Date : Page No. : 1/4 PL7905XE3 Description The PL7905XE3 series of three-terminal negative regulators are available in the TO-220AB package. These regulators can provide TO-220AB local on-card regulation, eliminating the distribution problems associated with single point regulation. Each employs internal current limiting, thermal shutdown and safe operating area protection, making it essentially 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. PL7905XE3 is characterized for operation from 0°C to +125°C, and if operating temperature is always high, please refer to the power dissipation curve. Absolute Maximum Ratings (Ta=25°C) • Input Voltage ...................................................................................................................... -35 V • Total Power Dissipation .................................................................................... Internally limited • Operating Junction Temperature ....................................................................... 0 °C to +125 °C • Maximum Junction Temperature ..................................................................................... 125 °C • Storage Temperature Range .......................................................................... -55 °C to +150 °C • Lead Temperature (Soldering 10S) ................................................................................. 230 °C Typical Application Schematic Diagram 1.4k GND Vin 2 PL7905 1 3 Vout 4K 7K 5K 15K C1 C2 3K 10K Vout 6.2V Note: Bypass Capacitors are recommended for optimum stability and transient response and should be located as close as possible to the regulator. 750 Vin 1K 6K 20K 20K 20pF 10pF 600 15K 20K 20K 5K 150 0.2 PL7905E3 CYStek Product Specification CYStech Electronics Corp.
