Reviewer: from Berkeley, CA US

200mA. Vin-Vout=1.25V to 37V (no limit on voltage otherwise). Requires 2 resistors to regulate: Vout = 1.25(1 + R2/R1). R1 usually = 240 ohm. Pinout (left to right, bottom view): ADJ, Vout, Vin. Connect R1 to Vout and ADJ. Connect R2 to ADJ and ground. If your output has any capacitance then protect the regulator from backflow surges with a diode. Can also be used as a current regulator if you replace R2 with your device (I = 1.2/R1).
