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.

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.

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.
