Low Consumption VOLTAGE REGULATOR
(Operating Voltage up to 36V)
NO. EA-152-070328
R1514x SERIES
OUTLINE
The R1514x series are CMOS-based positive voltage regulator (VR) ICs. The R1514xxxxxx has features of
high input voltage operating, 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 R1514x series.
The regulator output voltage is fixed in the R1514xxxxB. Output voltage accuracy is ±2.0%.
Since the packages for these ICs are the SOT-89-5 and HSOP-6J, high density mounting of the ICs on boards
is possible.
FEATURES
• High Output Voltage Accuracy......................................±2.0%
• Wide Output Voltage Range.........................................Stepwise setting with a step of 0.1V in the range of
2.0V to 12.0V(xxxB)
• Ultra-Low Supply Current.............................................Typ. 9.0µA
• Standby Current ...........................................................Typ. 0.1µA
• Input Voltage.................................................................Max. 36.0V
• Output Current..............................................................Min. 150mA (VIN=VOUT+3.0V; 5V Output type)
• Built-in Peak Current Limit Circuit, Short Current Limit Circuit, Thermal Shutdown Circuit
• Packages......................................................................SOT-89-5, HSOP-6J
• Operating Temperature ................................................-40°C to 105°C
APPLICATIONS
• Power source for home appliances such as refrigerators, rice cookers, electoric water warmers, etc.
• Power source for car audio equipment, car navigation system, ETC system, etc.
• Power source for notebook PCs, digital TVs, cordless phones, and private LAN system, etc.

TECHNICAL NOTES
Phase Compensation
Phase Compensation of the R1514x 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 rather large COUT, transient response will be improved.
Recommended value is in the range from 0.1µF to 10µF. 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.
GND wiring of mounting on board
No.2 pin and No.4 pin of SOT89-5 package must be wired to the GND plane. No. 2 pin, No.5 pin, and No.4 pin
must be wired to the GND plane when it is mounted on board.
13
R1514x
Thermal Shutdown
Thermal shutdown function is included in the R1514x 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. Otherwise, the
output voltage would be unstable or indefinite, or unexpected current would flow internally.
