1 / 19 page Actual Size (3 mm x 3 mm) TPS71202-EP www.ti.com SGLS395A – OCTOBER 2008 – REVISED SEPTEMBER 2010 DUAL, 250-mA OUTPUT, ULTRA-LOW NOISE, HIGH PSRR, LOW-DROPOUT LINEAR REGULATOR Check for Samples: TPS71202-EP 1 FEATURES SUPPORTS DEFENSE, AEROSPACE, AND MEDICAL APPLICATIONS • Dual 250-mA High-Performance RF LDOs • Controlled Baseline • Adjustable Output Voltage (1.2 V to 5.5 V) • One Assembly/Test Site • High PSRR: 65 dB at 10 kHz • One Fabrication Site • Ultra-Low Noise: 32 mVrms • Available in Military (–55°C/125°C) • Fast Start-Up Time: 60 ms Temperature Range(1) • Stable with 2.2-mF Ceramic Capacitor • Extended Product Life Cycle • Excellent Load/Line Transient Response • Extended Product-Change Notification • Very Low Dropout Voltage: 125 mV at 250 mA • Product Traceability DESCRIPTION • Independent Enable Pins • Thermal Shutdown and Independent Current The TPS71202 low-dropout (LDO) voltage regulator Limit is tailored to noise-sensitive and RF applications. It features dual 250-mA LDOs with ultra-low noise, high • Available in Thermally-Enhanced SON power-supply rejection ratio (PSRR), and fast Package: 3 mm × 3 mm × 1 mm transient and start-up response. Each regulator output is stable with low-cost 2.2-mF ceramic output APPLICATIONS capacitors and features very low dropout voltages • Cellular and Cordless Phones (125 mV typical at 250 mA). The regulator achieves • Wireless PDA/Handheld Products fast start-up times (approximately 60 ms with a 0.001-mF bypass capacitor) while consuming very low • PCMCIA/Wireless LAN Applications quiescent current (300 mA typical with both outputs • Digital Camera/Camcorder/Internet Audio enabled). When the device is placed in standby • DSP/FPGA/ASIC/Controllers and Processors mode, the supply current is reduced to less than 0.3 mA typical. The regulator exhibits approximately 32 mVrms of output voltage noise with VOUT = 2.8 V and a 0.01-mF noise reduction (NR) capacitor. Applications with analog components that are noise-sensitive, such as portable RF electronics, benefit from high PSRR, low noise, and fast line and load transient features. The TPS71202 is offered in a thin 3-mm × 3-mm SON package and is fully specified from –55°C to 125°C (TJ).
