AP1122 ANACHIP [Anachip Corp], AP1122 Datasheet - Page 3

• Manufacturer Part Number: AP1122
• Description: 1A Low Dropout Positive Regulator
• Manufacturer: ANACHIP [Anachip Corp]

Note1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured
Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the
Note3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the

not sag below the minimum dropout voltage during the load transient response.
This pin must always be 1.3V higher than Vout in order for the device to regulate
