AND MEDICAL APPLICATIONS• Dual 250-mA High-Performance RF LDOs Controlled Baseline• Adjustable Output Voltage (1.2Vto 5.5V) One Assembly/Test Site• High PSRR:65 dBat10 kHz • One Fabrication Site• Ultra-Low Noise:32 mVrms
• Availablein 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 mVat 250 mA • Product Traceability
DESCRIPTION• Independent Enable Pins Thermal Shutdown and Independent Current The TPS71202 low-dropout (LDO) voltage regulator
Limit is tailoredto noise-sensitive and RF applications.It
features dual 250-mA LDOs with ultra-low noise, high
• Availablein Thermally-Enhanced SON power-supply rejection ratio (PSRR), and fast
Package:3 mm×3 mm×1 mm transient and start-up response. Each regulator
outputis stable with low-cost 2.2-mF ceramic output
APPLICATIONS capacitors and features very low dropout voltages
• Cellular and Cordless Phones (125 mV typicalat 250 mA). The regulator achieves
Wireless PDA/Handheld Products fast start-up times (approximately 60 ms witha
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 currentis reduced to less than
0.3 mA typical. The regulator exhibits approximately mVrmsof output voltage noise with VOUT= 2.8V
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 TPS71202is offeredina
thin 3-mm× 3-mm SON package and is fully
specified from –55°Cto 125°C (TJ). available
