Overview
TDA8139, TDA8139/D Double (5.
1 V and adjustable) voltage regulator with reset and disable functions Features OUTPUT2 can be disabled via the TTL input.
■ Input voltage range: 7 V to 18 V ■ Output currents up to 750 mA Short-circuit and thermal protections are included in all versions.
■ Fixed Precision output 1 voltage: 5.
1 V ±2% ■ Adjustable output 2 voltage: 2.
8 to 16 V ■ Output 1 with reset function ■ Output 2 with disable function by TTL input )■ Short-circuit protection at both outputs t(s■ Thermal protection c■ Low dropout voltage roduDescription PThe TDA8139 and the TDA8139/D are monolithic tedual positive voltage regulators designed to leprovide a fixed precision output voltage of 5.
1 V oand an adjustable voltage between 2.
8 and 16 V sfor currents up to 750 mA.
bAn internal reset circuit generates a reset pulse - Owhen the voltage of OUTPUT1 drops below the )regulated voltage value.
