The Leader in High Temperature Semiconductor Solutions High-Temperature Automotive Adjustable, Linear Voltage Regulator +3.0V to +28V / 50mA CXT-STA4919- Preliminary Datasheet Version: 1.0 (see note 1) General description Features
CXT-STA4919 is part of the new CXT • Junction operating temperature from series of components designed and qual- -55°C to 175°C ified for high-temperature automotive en- vironments. • Input voltage from 4.5V to 30V, with input It is a high-temperature, high-reliability, transient (Load dump) up to 35V 50mA adjustable linear voltage regulator • Output voltage: from 3.0V to 28V suitable to generate from a +4.5V to • Output voltage total accuracy: ±5%2 +30V voltage source any regulated volt- age in the range +3.0V to +28V. Its oper- • Output current: 50mA max ating junction temperature ranges from • Min voltage dropout @ 50mA: 0.7V -55°C to +175°C, in excess of AEC-Q100 • Grade 0 automotive qualification stand- Line regulation: -1% max ard. The regulator is self-protected with a • Load regulation: -0.2% max built-in current limiter and a thermal pro- • C tection. CXT-STA4919 brings unique out: min 1 µF benefits in applications where the ambi- • Chip Enable ent or operating temperature is high and • Input ripple rejection: 65dB typ @ 100Hz above the temperature supported by tra- ditional semiconductors. • Quiescent current: 1.1 mA typ. The IC features a chip-enable (CE active • Stand-by current: 40 µA typ. low) input signal allowing placing the cir- • Current limitation cuit in low-power, disable mode. • Latch-up free The output voltage is adjustable by an external feedback resistor network. • PSOIC8 Package with exposed pad CXT-STA4919 is available in a tiny plas- • AEC-Q100 Grade 0 & PPAP capable3 tic package PSOIC8 with exposed pad for small PCB footprint and low thermal resistance.
