R1154x SERIES
150mA Voltage Regulator (Wide Input Voltage Range)
NO.EA-100-061107
OUTLINE
The R1154x series are CMOS-based voltage regulator (VR) ICs. The R1154xxxxxx has features of high output voltage accuracy and ultra-low supply current. A peak current limit circuit, a short current limit circuit, and a thermal shutdown circuit are built in the R1154x series. The regulator output voltage is fixed in the R1154xxxxB, while adjustable type is the R1154x001C. Output voltage accuracy is ±2.0%. Since the packages for these ICs are the SOT-89-5 and SOT-23-5, high density mounting of the ICs on boards is possible.

TECHNICAL NOTES
Phase Compensation Phase Compensation of the R1154x Series has been made internally for stable operation even though the load current would vary. Therefore, without the capacitors, CIN and COUT, the output voltage is regulated, however, for more stable operation, use capacitors as CIN and COUT. Especially, if the input line is long and impedance is high, CIN is necessary, moreover, if you use COUT, transient response will be improved. Recommended value is in the range from 0.1µF to 2.2µF. Wiring should be made as short as possible. Connect the capacitor, CIN between VDD pin and GND pin and COUT between VOUT and GND as close as possible.

Thermal Shutdown Thermal shutdown function is included in the R1154x Series, if the junction temperature is equal or more than +150°C(Typ.), the operation of regulator would stop. After that, when the junction temperature is equal or less than +125°C(Typ.), the operation of regulator would restart. Unless the cause of rising temperature would remove, the regulator repeats on and off, and output waveform would be like consecutive pulses. Chip Enable Circuit Do not make voltage level of chip enable pin keep floating level, or in between VIH and VIL. Unless otherwise, Output voltage would be unstable or indefinite, or unexpected current would flow internally. * Technical Notes on Output Voltage Setting of C type Figure 1.

The Output Voltage of Regulator in R1154xxxxC may be adjustable for any output voltage between its 2.5V reference and its VDD setting level. An external pair of resistors is required, as shown in Figure 1. The complete equation for the output voltage is described step by step as follows; I1=IIC+I2..................................................................................................................................... (1) I2=2.5/R2 .................................................................................................................................. (2) Thus, I1=IIC+2.5/R2 ............................................................................................................................. (3) Therefore, VOUT=2.5+R1×I1 ........................................................................................................................ (4) Put Equation (3) into Equation (4),then VOUT=2.5+R1(IIC+2.5/R2) =2.5(1+R1/R2)+R1×IIC ....................................................................................................... (5) In 2nd term, or R1×IIC will produce an error in VOUT. In Equation (5), IIC=2.5/RIC .................................................................................................................................. (6) R1×IIC=R1×2.5/RIC =2.5×R1/RIC .................................................................................................................... (7) For better accuracy, choosing R1 (
