RP170N501B-TR-FE Nisshinbo

RP170Q (SC-88A) is the discontinued product as of April, 2016. RP170x SERIES 300mA 10V INPUT LDO REGULATOR No.EA-205-200219 OUTLINE The RP170x is LDO regulator featuring 300mA output current. Because of the 10V maximum input voltage, RP170x can be used in 2 cell lithium-ion battery powered portable appliances and besides a portable equipment. The supply current is Typ. 23A though an excellent response characteristics. The output voltage range from 1.2V is possible. The output voltage accuracy and temperature-drift coefficient of output voltage of the RP170x Series are excellent. RP170x has a fold-back protection circuit and a thermal shutdown circuit. Moreover, a standby mode with ultra low supply current can be realized with the chip enable function. SC-88A, SOT-23-5 and SOT-89-5 with high power dissipation packages are available. FEATURES Supply Current Typ. 23A Standby Mode Typ. 0.1A Dropout Voltage Typ. 0.20V (IOUT=100mA, VOUT=3.0V) Typ. 0.77V (IOUT=300mA, VOUT=2.8V) Ripple Rejection Typ. 70dB (f=1kHz) Temperature-Drift Coefficient of Output Voltage Typ. 80ppm/C Line Regulation Typ. 0.02%/V Output Voltage Accuracy 1.0% Packages SC-88A, SOT-23-5, SOT-89-5 Input Voltage Range 2.6V to 10.0V Output Voltage Range 1.2V to 6.5V (0.1V steps) (For other voltages, please refer to MARK INFORMATIONS.) Built-in Fold Back Protection Circuit Typ. 40mA (Current at short mode) Built-in Thermal Shutdown Circuit Shutdown Temperature at 165C Built-in Constant Slope Circuit (Soft-start Function) Ceramic capacitors are recommended to be used with this IC 1.0F or more APPLICATIONS Power source for portable communication equipment. Power source for electrical appliances such as cameras, VCRs and camcorders. Power source for battery-powered equipment. Power source for home appliances. 1 RP170Q (SC-88A) is the discontinued product as of April, 2016. RP170x No.EA-205-200219 SELECTION GUIDE (1) The output voltage, auto discharge function, and package for the ICs can be selected at the users request. Product Name Package Quantity per Reel Pb Free Halogen Free RP170Qxx2-TR-FE SC-88A 3,000 pcs Yes Yes RP170Nxx1-TR-FE SOT-23-5 3,000 pcs Yes Yes SOT-89-5 1,000 pcs Yes Yes RP170Hxx1-T1-FE xx : The output voltage can be designated in the range from 1.2V(12) to 6.5V(65) in 0.1V steps. The voltage in 0.05 V step is shown as follows. Example 1.25 V: RP170x12x5 : The auto discharge function at off state are options as follows. (B) without auto discharge function at off state (D) with auto discharge function at off state BLOCK DIAGRAMS RP170xxxxB RP170xxxxD VDD VOUT VDD VOUT Vref Vref Current Limit Current Limit Thermal Shutdown Thermal Shutdown CE CE GND GND (1) Auto-discharge function quickly lowers the output voltage to 0V by releasing the electrical charge accumulated in the external capacitor when the chip enable signal is switched from the active mode to the standby mode. 2
