INTEGRAL ILA8137

ILA8137
+5.1 V +5.1 V REGULATOR WITH DISABLE AND RESET
The ILA8137A is a monolithic dual positive voltage regulator
designed to provide fixed precision output voltages of 5.1V at
current up to 0,75 A.
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 in ILA8137
