Description:

The NTE961 is a negative voltage regulator in a TO220 type package that employs current limiting, thermal shutdown, and safe-area compensation which makes it remarkably rugged under most operating conditions. With adequate heat sinking the NTE961 can deliver output currents in excess of 1 amp.

Features:

• No External Components Required
• Internal Thermal Overload Protection
• Internal Short-Circuit Current Limiting
• Output Transistor Safe-Area Compensation

Absolute Maximum Ratings:

Input Voltage, VIN		-35V
Input-Output Differential		25V
Internal Power Dissipation (Note 1), PD		Internally Limited
Operating Junction Temperature Range, TJ		0°C to +125°C
Storage Temperature Range, Tstg		-65°C to +150°C
Lead Temperature (During soldering, 10sec., TL		+230°C

Note 1.

For calculations of junction temperature rise due to power dissipation, thermal resistance junction to ambient (RthJA) is 50°C/W (no heat sink) and 5°C/W (infinite heat sink).

Electrical Characteristics: (V_OUT = -5V, V_IN = -10V, I_O = 500mA, C_IN = 2.2µF, C_OUT = 1µF, P_D = 1.5W unless otherwise specified)

Note 2.

Regulation is measured at a constant junction temperature by pulse testing with a low duty cycle. Changes in output voltage due to heating effects must be taken into account.
