Integrated Circuit
Positive 3 Terminal Voltage Regulator,
24V, 1.5A
Description:
The NTE1924 is a monolithic voltage regulator integrated circuit in a TO3 type package designed for
use in applications requiring a well regulated positive output voltage. Outstanding features include
full power usage up to 1.5A of load current, internal current limiting, thermal shutdown, and safe area
protection on the chip, providing protection of the series pass Darlington, under most operating condi-
tions. A low noise, temperature stable band gap reference is the key design factor insuring excellent
temperature regulation. This, coupled to a very low output impedance, insures superior performance
and load regulation.
Features:

Note 1. Short circuit protection is only assured to VIN max. In case of short circuit with input–output
voltages approaching VIN max, regulator may require the removal of the input voltage to restart.
Note 2. For operation above TC = +87.5°C, derate @ 400mW/°C.

Note 3. Low duty cycle pulse testing with Kelvin connectors required. Die temperature changes
must be accounted for separately.
Note 4. BW = 10Hz to 100kHz.
Note 5. Ripple attenuation is specified for a 1Vrms, 120Hz, input ripple. Ripple attenuation is mini-
mum of 60dB at 5V output and is 1dB less for each volt increase in the output voltage.
