Technical content

VOLTAGE REGULATOR(with Wide Input Voltage Range) with RESET NO.EA-081-0610 OUTLINE The R1150H series are CMOS-based voltage regulator (VR) ICs equipped with a voltage detector (V DET). VR function of the R1150Hxxxx has featur es of low dropout voltage, high ou tput voltage accura cy, and ultra-low supply current. Each of the R1150HxxxA types includes also a chip enable circuit. The output of built-in voltage detector is Nch open drain type. The R1150HxxxC/D types have a pin for connecting external capacitor to set a certain reset delay time instead of chip enable control pin. The regulator output voltage and the detector threshold voltage are fixed in the IC, Output Voltage Accuracy is ±2.0%, while Detector Threshold Accuracy is ±2.5%. The R1150HxxxA (with chip enable function) and C series can supervise input voltage by the built-in detector. R1150HxxxB type can supervise SENSE pin voltage by the built-in detector. R1150HxxxD type can supervise VOUT voltage, or Regulator Output Voltage of this IC itself. Since the package for these ICs is the SOT-89-5 pack age, high density mounting of the ICs on boards is possible.

Phase Compensation of the R1150H Series has been m ade internally for stable operation even though the load current would vary. Therefore, without the capacitors, C IN and C OUT, Output Voltage is regulated, but for more stable operation, use 0.1µF or more capacitors as C IN and C OUT. Wiring should be made as short as possible. PCB layout Current flows into wiring for V DD or GND, thus, if the impedance of the wiring is rather high, it may cause of making noise or unstable operation, thus width and pattern should be enough wide to avoid such problems. Connect the capacitor, C IN between VDD pin and GND pin as close as possible. 470kΩ VDD 4VDET R1150HxxxA Typical Application Thermal Shutdown Thermal shutdown function is included in the R11 50HxxxA/B/C/D Series, when 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 +120°C (Typ.), the oper ation 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 V IH and VIL. Unless otherwise, Output voltage would be unstable or indefinite, or unexpected current would flow internally.

Output Delay Time for Release VDET In the R1150Hxx1C/D can set an output delay time for release voltage detector with connecting a capacitor to CD pin. When an input voltage (in the case of R1150Hxx1 C) or an output voltage (in the case of R1150Hxx1D) surpasses the release voltage of its voltage detector (+VDET), the capacitor which is connected to CD pin is started to be charged, as a result, CD pin voltage rises. When the CD pin voltage surpasses CD pin threshold voltage, the output voltage of the voltage detector outputs “H”. Input Voltage or Output Voltage C D Pin Voltage Output Voltage Output Delay Time (tpLH) GND GND C D Pin Threshold Voltage Released Voltage (+VDET ) Output delay time for release voltage detector can be calculated with the next formula: tpLH=1.25/200×109×C (sec) Input Transient Response If input transient is 0.12V/µs or faster, the output response may be extremely worse than normal operation. In that case, add a capacitor between VIN and GND, and make the transient speed of VIN slower than 0.12V/µs.
