TDA8137

DUAL 5.1V REGULATOR WITH DISABLE AND RESET

. OUTPUT CURRENTS UP TO 1A

. FIXED PRECISION OUTPUT VOLTAGES

5.1V ± 2%

. OUTPUT 1 WITH RESET FACILITY

. OUTPUT 2 WITH DISABLE BY TTL INPUT

. SHORT CIRCUIT PROTECTION AT BOTH

OUTPUTS

. THERMAL PROTECTION

. LOW DROP OUTPUT VOLTAGE

DESCRIPTION

The TDA8137 is a monolithic dual positive voltage

regulator designed to provide fixed precision output

voltages of 5.1V at currents up to 1A.

An internal reset circuit generates a reset pulse

when the output 1 decreases below the regulated

voltage value.

Output 2 can be disabled by TTL input.

Short circuit and thermal protections are included.
