DESCRIPTION
The SPX385-5.0 is a micropower 2-terminal band-gap voltage reference with a very wide
operating current range from 50µA to 20mA that provides a stable voltage.
The SPX385-5.0 is available in SOT-23, TO-92, NSOIC, and SOT-89 packages with an
operating temperature range of -40°C to 85°C. A 1.2 and 2.5 volt device are also available -
SPX385-1.2, SPX385-2.5.

ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
Reverse Current (IKA) ............................................................. 30mA
Forward Current (IAK) ............................................................. 10mA
Operating Temperature Range (TA) ............................ -40 to +85°C
Junction Temperature (T ) ..................................................... 150°C
Storage Temperature (T J ) ....................................... - 65 to 150°C
Lead Temperature (SoldSeTrGing 10 sec.), TL ............................. 300°C
ELECTRICAL CHARACTERISTICS
IIN = 100µA, TA = 25°C, unless otherwise specified. The ♦ denotes the specifications which apply over the full operating
temperature range.
