LM317T Voltage Regulator with Pass Transistor

The RGi-AWC-1 (Advanced Wireless Controller) is a 6.2in x 5in (15.75cm x 12.75cm) dual CPU board that embodies a complete robotics control system and development platform. It communicates via wireless 802.11b/g WiFi or 802.15.4 ZigBee communications standards. The internal resources include the following: ------------------------------------------------------------ • A 10-channel R/C servo controller with 180-degree range (500µs to 2.5ms pulse) and automatic internal/external power switchover. • A dual high-efficiency motor controller with a capacity of 45A per motor, precision current sensing and limiting, and programmable motor soft start. • 13 analog inputs with input protection, filters and 10-bits of resolution. • A 32 channel Dynamixel AX/DX servo controller with 300-degree range, 1024 steps, and programmable rpm, torque and offsets. • A powerful 15A PWM output with 255 steps, capable of switching internal battery and external battery sources. • A unique power management system with programmable sleep times, inactivity timeout and direct sleep modes, switchable output power for webcam, motor and radio sections. • A high-efficiency, wide-input range, switching, step-down, voltage regulator that provides 6.0V at 3A. • A separate voltage regulator that provides 5.0V at 1A, with a powerful 25A switching FET for output power, used for remote power management of webcams, video cameras, etc. • An additional voltage regulator that provides 3.3V ad 1A, used for the radio ...
