Notes:

Additional conditions for GM2951 series are the FB tied to V_TAPand V_OUTTied to SENSE and V_SD≤ 0.8V

Output or Reference voltage temperature coefficients are defined as the worst case voltage change divided

by the total temperature range.

The Regulation is measured at a constant junction temperature using pulse testing with a low duty cycle.

Changes in the output voltage due to heating effects are covered under the specification for thermal

regulation.

The Dropout voltage is defined as the input-to-output differential, at which the output voltage drops 100mV

below it nominal value measure at 1V differential. At very low values of programmed output voltage, the

minimum input supply voltage (2V) (2.3V over temperature) must be taken into account.

V_REF≤ V_OUT≤ (V_IN-1V), 2.3V ≤ V_IN≤ 30V, 100μA ≤ I_OUT≤ 100mA, T_J≤ T_JMAX

Comparator thresholds are expressed in terms of a voltage differential at the FB terminal below the nominal

reference voltage measured at V_OUT+ 1V input. To express these thresholds in terms of an output voltage

change, multiply by the error amplifier gain = V_OUT/V_REF= (R1 + R2)/R2. For examples, at a programmed

output voltage of 5V, the Error output is guaranteed to go low when the output drops by 95mV x 5V/1.235V

= 384mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the dropout warning

occurring at typically 5% below nominal, 7.5% guaranteed.

V_SD≥ 2V, V_IN≤ 30V, V_OUT= 0, the FB pin is tied to V_TAP.
