DESCRIPTION
The LT ? 3015 series are low noise, low dropout, negative
linear regulators with fast transient response. The devices
supply up to 1.5A of output current at a typical dropout
voltage of 310mV. Operating quiescent current is typically
1.1mA and drops to < 1μA in shutdown. Quiescent current
is also well controlled in dropout. In addition to fast tran-
sient response, the LT3015 series exhibit very low output
noise, making them ideal for noise sensitive applications.
The LT3015 regulators are stable with a minimum 10μF
output capacitor. Moreover, the regulator can use small
ceramic capacitors without the necessary addition of ESR
as is common with other regulators. Internal protection
circuitry includes reverse output protection, precision cur-
rent limit with foldback and thermal limit with hysteresis.
The LT3015 regulators are available in fixed output volt-
ages of –2.5V, –3V, –3.3V, –5V, –12V and –15V and as an
adjustable device with a –1.22V reference voltage. Pack-
ages include the 5-lead TO-220 and DD-Pak, a thermally
enhanced 12-lead MSOP and the low profile (0.75 mm)
8-lead 3mm × 3mm DFN.
