Data Sheet 600mA LOW DROPOUT LINEAR REGULA 600mA LOW DROPOUT LINEAR REGULATTOORR AP2317 AP1117M LOW DROPOUT LINEAR REGULATOR AZ1117B General Description Features The AZ1117B is a low dropout three-terminal regula- Current Limit: 1.0A (Typ.) tor. Output Noise from 10Hz to 10KHz: 0.003% of V OUT The AZ1117B has been optimized for low voltage PSRR at I =300mA and f=120Hz: 70dB OUT where transient response and minimum input voltage Output Voltage Accuracy: 1% are critical. It provides current limit and thermal shut- On-chip Thermal Shutdown down. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1%. Maximum Quiescent Current: I =6mA QMAX On-chip thermal shutdown provides protection against o Operation Junction Temperature: -20 to 125 C a combination of high current and ambient temperature that would create excessive junction temperature. Applications The AZ1117B is available in 1.2V, 1.5V, 1.8V, 2.5V, USB Device 3.3V, 5.0V fixed output voltage vesions and ADJ out- Add-on Card put voltage version. The fixed versions integrate the adjust resistors. It is also available in an adjustable ver- DVD Player sion which can set the output voltage with two external PC Motherboard resistors. The AZ1117B is available in the industry-standard TO- 252-2 (1), TO-252-2 (2), TO-252-2 (3), SOT-223 and SOT-89 power packages. SOT-223 SOT-89 TO-252-2 (1) TO-252-2 (2) TO-252-2 (3) Figure 1.
