Typical Application for OM8506SF +7.5Vin, +6.1 to +7 Vout @ 3A Ultra Low-Dropout Linear Regulator. The OM8506 is an ultra low dropout adjustable linear regulator designed specifically for hi-rel applications. Housed in either a 5 pin through hole or 8 lead surface mount package, these regulators provide high reliability in military/defense applications. The ultra low dropout voltage of 0.4V @ 3A makes the part particularly useful for applications requiring low noise and higher efficiency
