XB1117 series

1.0A LDO Voltage Regulator

The XB1117 series is a 1A low-dropout positive voltage regulator, available with 1.8V, 2.5V, 3.3V, and 5.0V fixed output voltages (XB1117P).  An adjustable output voltage variant is also available (XB1117K) where the voltage is set by external resistors. The maximum input voltage of the fixed 5.0V part is 10V, and the maximum input voltage for the 1.8V, 2.5V and 3.3V parts as well as the adjustable variant is 7V.

A max 1A output current can be generated with a low 1.2V (typ) dropout voltage. The built-in over-current and thermal protection circuits operate when either output current reaches the current limit level or junction temperature reaches 150°C. The XB1117 series provides stable input and load stability as well as stable temperature variation by using 10µF tantalum capacitors for the input (CIN) and output (CL). The XB1117 is available in a SOT-223 package, with a power dissipation of 625mW @ 100°C.
