R1152N

R1152N SERIES High Input Voltage Tolerant Boost Voltage Regulator NO.EA-108-0601 OUTLINE The R1152N Series are CMOS-based positive voltage regulator controller ICs with high output voltage accuracy, low supply current. The high output current regulator can be composed with this IC, an external power transistor, and capacitors. Each of these voltage regulator controllers consists of a voltage reference unit, an error amplifier, comparators, resistors for output voltage setting, a peak current limit protection circuit, a short current limit circuit, and a chip enable circuit. The output voltage of these ICs is internally fixed. In addition to low supply current by the merit of CMOS process, the chip enable function prolongs the battery life. Maximum operating input voltage is up to 18V, thus these ICs are very suitable for the power supply for hand-held equipment and other power management applications using various AC adapters. Since the package for these ICs is SOT-23-5 package, high density mounting of the ICs on boards is possible.

The base current is monitored with the base current limit circuit. If the base current may be too large, the protection circuit works. TECHNICAL NOTES When using these ICs, consider the following points: Make VDD and GND lines sufficient. When their impedance is high, noise pickup or unstable operation may result. When you choose an external transistor, select with considering output current, input voltage, and power dissipation. Generally, low VCE(SAT) and hFE range from 100 to 300 are the appropriate characteristics. In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, be sure to use a 10µF or more output capacitor, as close as possible to the ICs. If you choose an electrolytic capacitor, ESR shift by temperature should be small. If you choose a ceramic capacitor, add an appropriate series resister. If the set output voltage is less than 4.0V, and IOUT>1A must be obtained, at least VIN≧5.0V is the appropriate condition. (Supposed as hFE=100) Voltage level for CE should not be floating, or middle range voltage. If the CE voltage is not appropriate, output voltage may be unstable or conduction current may flow. All external components should be located as close as possible to the IC, and wiring should be as short as possible. If hFE value of the PNP transistor is too high, output voltage may rise at low load current (less than 1mA). 6 R1152N TEST CIRCUITS ISS VIN CE VIN CIN EXT VOUT PNP Tr OUT VIN CE VIN EXT VOUT GND COUT GND VOUT Fig.1 Standard test Circuit CIN=0.1µF, COUT=10µF Fig.2 Supply Current Test Circuit VIN VIN EXT VOUT GND PNP Tr IOUT OUT COUT VIN CIN CE EXT VOUT PNP Tr OUT P.G.
