100mA / 3-TERMINAL
NEGATIVE VOLTAGE REGULATOR
A
DD MICROTECH CORP.
DESCRIPTION FEATURES
The AMC79L05 is a 3-terminal fixed negative-voltage
designed for a wide range of applications. This regulator
can provide local on card regulation, eliminating the
distribution problems associated with single point
regulation. In addition, it can be used with power-pass
elements to make high-current voltage regulators with
100mA output current.
Protection features such as thermal shutdown and current
limiting have been designed internally which will protect
the device from damage in case of overload or
overheating.
±5% tolerance of output voltage
Wide input range
Internal thermal overload protection
Output current > 100mA
No External Components
Short circuit protection
Available in 3L plastic TO-92 and
plastic 8 pin S.O.I.C.
Identical pin assignment to earlier
79L05 series.

Input Voltage -30V
Operating free-air temperature range, TA 0OC to 70 OC
Storage temperature range -65OC to 150OC
Lead temperature (soldiering, 10 seconds) 260 OC
Note 1: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground.
Currents are positive into, negative out of the specified terminal.
THERMAL DATA
LP PACKAGE:
Thermal Resistance-Junction to Ambient, θJA 156 OC/W
DM PACKAGE:
Thermal Resistance-Junction to Ambient, θJA 165 OC/W
Junct ion Temperatur e Calculation: TJ = TA + (PD × θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board system.
All of the above assume no ambient airflow.

Unless otherwise specified, these specifications in bold type apply over the operating temperature range of
0OC ≤ TJ ≤ +150OC, VIN = -10V,IOUT = 40mA,CIN = 0.33µF, COUT= 0.1µF, and are for DC characteristics only. (Low
duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.)
