R5325X

R5325x SERIES 150mA 2ch LDO REGULATOR NO.EA-127-0606 OUTLINE The R5325x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current (Typ. 3.0µA), low dropout, and fast transient response. 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 due to built-in transistor with low ON resistance, and a chip enable function prolongs the battery life of each system. The line transient response and load transient response of the R5325x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. The supply current at no load of R5325x Series is remarkably reduced compared with R5325x Series. The mode change signal to reduce the supply current is not necessary. The output voltage of these ICs is internally fixed with high accuracy (±1.0%) Since the packages for these ICs are SOT-23-6 and PLP1820-6 package, 2ch LDO regulators are included in each, high density mounting of the ICs on boards is possible.

GRM155B30J105KE18B 1.Mounting on PCB Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor with a capacitance value as much as 1.0µF or more as C1 between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor, as close as possible to the ICs, and make wiring as short as possible. 2.Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). (Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the PCB.) If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable. Evaluate your circuit with considering frequency characteristics. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit with actual using capacitors. 19 PACKAGE INFORMATION PE-SOT-23-6-0510 • SOT-23-6 (SC-74) Unit: mm PACKAGE DIMENSIONS 2.9±0.2 1.9±0.2 (0.95) (0.95) +0.2 1.1 −0.1 0.8±0.1 4 6 5 +0.2 1.6 −0.1 2.8±0.3 0 to 0.1 1 2 0.2 MIN. +0.1 0.4−0.2 +0.1 0.15 −0.05 TAPING SPECIFICATION 0.3±0.1 +0.1 φ1.5 0 4.0±0.1 2.0±0.05 1 2.0MAX. 2 3 4.0±0.1 3.3 ∅1.1±0.1 TR User Direction of Feed TAPING REEL DIMENSIONS (1reel=3000pcs) 11.4±1.0 9.0±0.3 21±0.8 0 180 −1.5 2±0.5 13±0.2 +1 60 0 3.2 8.0±0.3 6 5 4 3.5±0.05 1.75±0.1 PACKAGE INFORMATION PE-SOT-23-6-0510 POWER DISSIPATION (SOT-23-6) This specification is at mounted on board.
