代理普诚 RS1117A 低压差正电压调节器

DESCRIPTION

The RS1117A is a 1A low-dropout positive voltageregulator. It is available in fixed and adjustable outputvoltage versions. Over current and thermal protectionare integrated onto the chip. Output current will limitas while it reaches the pre‐set current or temperaturelimit. The dropout voltage is specified at 1.40VMaximum at full rated output current. The RS1117Aseries provides excellent regulation over line, loadａnd temperature variations.
