NTE988
Integrated Circuit
Positive 3 Terminal Voltage Regulator, 100mA
Description:
The NTE988 is a 3–terminal positive voltage regulator in a TO92 type package and employs internal
current–limiting and thermal shutdown, making it essentially indestructible. If adequate heat sinking
is provided, this device can deliver up to 100mA output current. The NTE988 is intended for use as
a fixed voltage regulator in a wide range of applications including local (on–card) regulation for elimi-
nation of noise and distribution problems associated with single–point regulation. In addition, this de-
vice can be used with power pass elements to make a high current voltage regulator. When used as
a Zener diode/resistor combination replacement, the NTE988 offers an effective output impedance
improvement of typically two orders of magnitude, along with lower quiescent current and lower noise.
Features:
D Output Current up to 100mA
D No External Components
D Internal Thermal Overload Protection
D Internal Short Circuit Current–Limiting

Note 1. The maximum steady state usable output current and input voltage are very dependent on
the heat sinking and/or lead length of the package. The data above represents pulse test
conditions with junction temperatures as indicated at the initiation of the tests.
