Logic high = enable, logic OUT FLG Regulator Output LM39100-X.X ADJ GND Adjustment Input: Feedback input. Connect to resitive voltage-divider network LM39101-X.X LM39102-Adj 1 LM39100- X.X SOT-223 Logic low or open = shutdown Supply (Input) Flag (Output): Open-collector error flag output. LM39101-X.X SOP-8 LM39102-Adj SOP-8 SOT-223 SOP-8 * X.X = Fixed Vout = 1.5V, 1.8V, 2.5V, 3.3V, 5.0V The LM39100, LM39101, and LM39102 are 1A low-dropout linear voltage regulators that provide low- voltage,high-current output from an extremely small package. The LM39100/1/2 offers extremely low dropout (typically 410mVat 1A) and low ground current (typically 12mA at 1A). The LM39100 is a fixed output regulator offered in theSOT-223 package. The LM39101 and LM39102 are fixedand adjustable regulators, respectively, in a thermally en-hanced power 8-lead SOP (small outline package). The LM39100/1/2 is ideal for PC add-in cards that need toconvert from standard 5V to 3.3V, 3.3V to 2.5V or 2.5V to1.8V. A guaranteed maximum dropout voltage of 630mV overall operating conditions allows the LM39100/1/2 to provide2.5V from a supply as low as 3.13V and 1.8V from a supplyas low as 2.43V. The LM39100/1/2 is fully protected with over current limiting,thermal shutdown, and reversed-battery protection. Fixed voltages of 5.0V, 3.3V, 2.5V,1.8V and 1.5V are available on LM39100/1 with adjustable output voltages to 1.24V on LM39102. |
