r1162x series 3-mode 150ma ldo regulator no.ea-110-0512 1 outline the r1162x series consist of cmos-based voltage regul ator ics with high output voltage accuracy and low supply current. each of these voltage regulator ics co nsists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circui t, and so on. the output voltage is internally fixed with high accuracy. these ics perform with the chip enable function and r ealize a standby mode with ultra low supply current. to prevent the destruction by over curren t, the current limit circuit is inclu ded. the r1162x series have 3-mode. one is standby mode with ce or standby control pin. other two modes are realized with eco pin?. fast transient mode (ft mode) and low power mode (lp mode) are alternative with eco pin?. consumption current is reduced at low power mode compared with fast transient mode. the output voltage is maintained between ft mode and lp mode. since the packages for these ics are sot-23-5 and son1 612-6 packages, high density mounting of the ics on boards is possible. features ? ultra-low supply cu rrent..................................typ. 5.5 a (low power mode), typ. 70 a (fast transient mode) ? standby mode ...................................................typ. 0.1 a ? low dropout voltage .........................................typ. 0.25v (i out = 150ma output voltage = 3.0v type) ? high ripple rejectio n .......................................typ. 70db (f = 1khz, ft mode) typ. 60db (f = 10khz, ft mode) ? low temperature-drift coefficient of output voltage typ. 100ppm/ c ? excellent line regula tion .................................typ. 0.02%/v ? high output vo ltage accu racy .......................... 2.0%( 3.0% at lp mode) ? small package ................................................so t-23-5 (super mini-mold), son1612-6 ? output voltage ..................................................st epwise setting with a step of 0.1v in the range of 1.5v to 4.0v is possible ? built-in fold-back protection circuit ....................typ. 40ma (current at short mode) ? performs with ceramic capacitors ...................c in = 1.0 f, c out = 0.47 f applications ? precision voltage references. ? power source for electrical appliances such as cameras, vcrs and hand-held communication equipment. ? power source for battery-powered equipment.
