precision-trimmed 2.5-V shunt regulator featuring

low dynamic impedance and a wide operating

current range. The maximum initial tolerance is

±5 mV in the LP package and ±10 mV in the

D package. The reference tolerance is achieved

by on-chip trimming, which minimizes the initial

voltage tolerance and the temperature

Although the LT1009 needs no adjustments, a

third terminal (ADJ) allows the reference voltage

to be adjusted ±5% to eliminate system errors. In

many applications, the LT1009 can be used as a

terminal-for-terminal replacement for the

LM136-2.5, which eliminates the external trim

network.

The LT1009 uses include 5-V system references, 8-bit ADC and DAC references, and power-supply monitors.

The device also can be used in applications such as digital voltmeters and current-loop measurement and

control systems.

The LT1009C is characterized for operation from 0°C to 70°C. The LT1009I is characterized for operation from

–40°C to 85°C.
