GENERAL DESCRIPTION
FEATURES
It provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference T to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature. E The AZ1117B is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed output voltage vesions and ADJ out- L put voltage version. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors.● Current Limit: 1.0A (Typ.)
● Output Noise from 10Hz to 10KHz: 0.003% of VOUT
