SC5205

The SC5205 is a 150mA ultra low dropout linear regulator with a built in CMOS/TTL logic level enable switch.It is designed specifically for battery powered applications where low quiescent current and low dropout are critical for battery longevity.

Features of the SC5205 are:(1)ultra low dropout voltage165mV@150mA; (2)guaranteed 150mA output current; (3)low ground pin current at all loads; (4)<5pA quiescent current in shutdown; (5)wide input supply voltage range 2.5V to 16V in wide output voltage range; (6)excellent line regulation; (7)industrial temperature range; (8)surface mount packaging (5 pin SOT-23).The SC5205 uses a Semtech proprietary internal PNP device for the pass element, providing a low dropout voltage of 165mV at a load of 150mA, while maintaining a ground pin current of 2750A.

The absolute maximum ratings of the SC5205 can be summarized as:(1)input supply voltage:-0.3 to 20V;(2)storage temperature range:-65 to 150;(3)operating junction temperature range:-40 to 125;(4)operating ambient temperature range:-40 to 85;(5)power dissipation:internally limited.Each device contains a bandgap reference,error amplifier, PNP pass element, thermal and current limiting circuitry and resistor divider network for setting output voltage.The SC5205 is packaged in a 5 pin SOT-23 surface mount package for a very small footprint and it requires only a 1F capacitor on the output and a 0.01pF on the bypass pin for a minimum amount of external components.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
