ELECTRICAL CHARACTERISTICS

Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7905A / SG7905 with -55°C < TA <

125°C, VIN = -10V, IO = 500mA for the K, G, and IG – Power Packages, IO = 100mA for the T and L packages, CIN = 2µF, and COUT =

1µF. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.

Test Conditions

TJ = 25°C

VIN = -7.5V to -25V, TJ = 25°C

VIN = -8V to -12V, TJ = 25°C

Power Pkgs: IO = 5mA to 1.5A, TJ = 25°C

IO = 250mA to 750mA, TJ = 25°C

T – Pkg: IO = 5mA to 500mA, TJ = 250°C

VIN = -8V to -20V

Power Pkgs: IO = 5mA to 1.0A, P < 20W

T – Pkg: IO =5mA to 500mA, P < 20W

Over Temperature Range

TJ = 25°C

With Line: VIN = -8V to -25V

With Load: IO = 5mA to 1.0A (Power Pkgs.)

IO = 5mA to 500mA (T)

∆VO = 100mV, TJ = 25°C

Power Pkgs: IO = 1.0A, T-Pkg: IO = 500mA

Power Pkgs: TJ = 25°C

T – Pkg: TJ = 25°C

Power Pkgs: VIN = -35V, TJ = 25°C

T – Pkg: VIN = -35V, TJ = 25°C

∆VIN = 10V, f = 120Hz, TJ = 25°C

f = 10Hz to 100kHz (Note 2)

1000 hours @ TJ = 125°C
