SNVS778E – MAY 1999 – REVISED JANUARY 2016

Feature Description (continued)

LM137

VOUT = −10 V

VIN − VOUT = −40 V

IIL = 0 A → 0.25 A → 0 A

Vertical sensitivity, 5 mV/div

Figure 13. Output Drift (10W Pulse for 10ms)

In Figure 13, a typical LM137 device's output drifts only 3 mV (or 0.03% of VOUT = −10 V) when a 10-W pulse is

applied for 10 ms. This performance is thus well inside the specification limit of 0.02%/W × 10 W = 0.2%

maximum. When the 10-W pulse is ended, the thermal regulation again shows a 3-mV step at the LM137 chip

cools off.

NOTE

The load regulation error of about 8 mV (0.08%) is additional to the thermal regulation

error.

In Figure 14, when the 10-W pulse is applied for 100 ms, the output drifts only slightly beyond the drift in the first

10 ms, and the thermal error stays well within 0.1% (10 mV).
