Средства разработки интегральных схем (ИС) управления питанием TPS73201DRBEVM-518

Оценочная плата , регулируемый линейный стабилизатор с LDO 250мА

The TPS73201DRBEVM-518 evaluation module is a fully assembled and tested circuit for evaluating the TPS732xx family of low dropout (LDO) voltage regulator in the DRB (3x3mm SON) package. The TPS732xx family of low dropout (LDO) voltage regulators uses a new topology an NMOS pass element in a voltage follower configuration. This topology is stable using output capacitors with low ESR, and even allows operation without a capacitor. It also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current. The TPS732xx uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 1µA and ideal for portable applications. The extremely low output noise (30µVRMS with 0.1µF CNR) is ideal for powering VCOs. These devices are protected by thermal shutdown and foldback current limit.

• Stable with no output capacitor or any value or type of capacitor
• Input voltage range from 1.7V to 5.5V
• 40mV Typ at 250mA ultra low dropout voltage
• Excellent load transient response, with or without optional output capacitor
• New NMOS topology provides low reverse leakage current
• 30uVRMS Typ (10KHz to 100KHz) low noise
• 0.5% initial accuracy
• 1% overall accuracy (Line, load, and temperature)
• Less than 1uA Max IQ in shutdown mode
• Adjustable outputs from 1.20V to 5.5V
