The A6300 has both thermal shutdown and current limiting to prevent device failure under extreme operating conditions. The A6300 features a typical 0.8Ω P-Channel MOSFET pass transistor. It provides several advantages over similar designs using PNP pass transistors, including longer battery life. The A6300 is available in SOT-23, SOT-25, TSOT-25 and SC70-5 package.  Fixed Output Voltage: 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V, 3.0V, 3.3V and 4.0V (Customized 0.1V Step Output Voltage)  Low Dropout Voltage: 0.18V@ 300mA (VOUT=3.3V)  High PSRR: 70dB @ 100Hz  Quiescent Current: 67uA ( Typ.)  Accurate within ±2%  Excellent Line and Load Regulation  Fast Response  Output Current Limit and Thermal Shutdown  Short Circuit Protection  Low Temperature Coefficient  Shutdown Current: 0.5uA  Available in SOT-23, SOT-25, TSOT-25 and SC70-5 package APPLICATION ORDERING INFORMATION Package Type Part Number SOT-23 A6300E3R-XXZ E3 A6300E3VR-XXZ SOT-25 E5 A6300E5R-XX A6300E5VR-XX TSOT-25 TE5 A6300TE5R-XX A6300TE5VR-XX SC70-5 C5 A6300C5R-XX A6300C5VR-XX XX: Output Voltage 25=2.5V, 33=3.3V… Note Z: A, B ( Package type, see pin description table) V: GREEN Package R: Tape & Reel AiT provides all Pb free products Suffix “V” means GREEN PACKAGE  Power Source for Mobile and various kind of PCs  Battery Powered Equipment  Power Management of MP3, PDA, DSC, Mouse, PS2 Games  Reference Voltage Source  Regulation after Switching Power  Notebook and Handheld equipment  Wireless LAN, Bluetooth, GPS Receivers  Cordless Phones  Radio Communication Equipment Typical Application REV1.2 - JUN 2006 RELEASED - SEP 2008 REVISED - 1 AiT Semiconductor Inc. www.ait-ic.com PIN DESCRIPTION A6300 LOW DROPOUT VOLTAGE REGULATOR 300mA CMOS WITH ENABLE PIN Top View SOT-23 AB 33 12 --21 Top View Pin # TSOT-25 C SOT-25 21 32 3 4 15 Top View SC70-5 1 2 3 4 5 Symbol VIN GND EN BP VOUT Top View Top View Function Input Voltage Pin Ground Pin Enable Pin (Active High) Bypass Pin Output Voltage Pin REV1.2 - JUN 2006 RELEASED - SEP 2008 REVISED - 2 AiT Semiconductor Inc. www.ait-ic.com A6300 LOW DROPOUT VOLTAGE REGULATOR 300mA CMOS WITH ENABLE PIN ABSOLUTE MAXIMUM RATINGS Input Voltage 6V Output Current 300mA Output Voltage GND -0.3V to VIN +0.3V Lead Soldering Temperature 300℃, 10sec Storage Temperature -65℃~150℃ Junction Temperature -40℃~+125℃ Ambient Temperature -40℃~+85℃ Thermal Resistance (Junction to Case, θJC) SOT-23 130℃/W SOT-25 130℃/W TSOT-25 130℃/W Thermal Resistance (Junction to Ambient, θJA) SOT-23 250℃/W SOT-25 250℃/W TSOT-25 250℃/W SC70 300℃/W Internal Power Dissipation ( PD ) SOT-23 SOT-25 400mW 400mW TSOT-25 400mW SC70 300mW Stresses above may cause permanent damage to the device.
