r1161x series 3-mode 300ma ldo regulator no.ea-106-0511 1 outline the r1161x series are cmos-based voltage regulator ics with high output voltage accuracy, low supply current, and low on-resistance. each of these voltage regulator ics consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. these ics perform with low dropout voltage and a chip enable function. to prevent the destruction by over current, current limit circuit is included. the r1161x series have 3-mode. one is standby mode with ce or standby control pin. standby mode realizes ultra small consumption current off mode. 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. output voltage is maintained between ft mode and lp mode. the output voltage of these ics is internally fixed with high accuracy. since the packages for these ics are sot-23-5, son-6, and hson-6, high density mounting of the ics on boards is possible. features x ultra-low supply current .................................typ. 3.5 p a (low power mode, v out <1.6v), typ. 80 p a (fast transient mode, v out <1.8v) ty p. 60 p a (fast transient mode, v out ! 1.8v) x st andby mode ...................................................typ. 0.1 p a x low dropout voltage.........................................typ. 0.48v(i out 300ma output voltage 1.0v type) typ. 0.31v(i out 300ma output voltage 1.5v type) typ. 0.23v(i out 300ma output voltage 3.0v type) x high ripple rejection .......................................typ. 65db(f 1khz, ft mode) x low temperature-drift coefficient of output voltage typ. 100ppm/ q c x excellent line regulation .................................typ. 0.01%/ v (at fast transient mode) x high output voltage accuracy .......................... r 2.0%( r 3.0% at lp mode) x small package ................................................sot-23-5 (s uper mini-mold), son-6, hson-6 x output voltage ..................................................stepwise setting with a step of 0.1v in the range of 0.8v to 3.3v is possible x input voltage .....................................................min. 1.40v(v out ! 1.0v) m in. 1.45v(v out <1.0v) x built-in fold-back protection circ uit ....................typ. 50ma (current at short mode) x external capacitors...........................................c in c out t antalum 1.0 p f (v out <1 . 0v) c in c out ceramic 1.0 p f (v out ! 1. 0v) applications x precision voltage references. x power source for electrical appliances such as cameras, vcrs and hand-held communication equipment. x power source for battery-powered equipment.
