ADR280ARTZ-REEL7

ADR280 is a 1.2V band gap core reference with excellent line regulation and power supply rejection designed specifically for applications experiencing heavy dynamic supply variations, such as data converter references in GSM, GPRS, and 3G mobile station applications. Devices such as the AD6535 that have an analogue baseband IC with on-board baseband, audio codecs, voltage regulators, and battery chargers rely on the ability of the device to reject input battery voltage variations during RF power amplifier activity. In addition to mobile stations, this device is suitable for a variety of general-purpose applications. Most band gap references include internal gain for specific outputs, which simplifies the user’s design, but compromises on the cost, form factor, and flexibility. It is widely used in application such as list GSM, GPRS, 3G mobile stations, portable battery-operated electronics, low voltage converter references, wireless devices etc.

• Excellent line regulation is 2ppm/V typical
• High power supply ripple rejection is -80dB typical at (LOAD = 10μA)
• Ultralow power supply current is 10μA typical at (2.4V <lt/> VIN <lt/> 5.5V, no load)
• Temperature coefficient is 40ppm/°C max at (VIN = 2.55V to 5.5V, TA = 25°C)
• Low noise is 12.5nV/√Hz typical at (f = 400KHz)
• Operating supply range is 2.4V to 5.5V
• Operating temperature is -40°C to +85°C
• Package style is 3-lead SOT-23
