The TPS73701DCQ is a linear low-dropout (LDO) Voltage Regulator uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1µF ceramic output capacitor. The NMOS topology also allows very low dropout. This device 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 less than 20nA and ideal for portable applications. This device is protected by thermal shutdown and fold-back current limit. It features reverse current blockage and freedom from output capacitor constraints. These features combined with an enable input makes the device ideal for portable applications.

• Thermal shutdown and current limit for fault protection
• Excellent load transient response-even with only 1µF output capacitor
• 1% Initial accuracy
• 3% Overall accuracy over line, load and temperature
• Less than 20nA typical IQ in shutdown mode
• Green product and no Sb/Br

The LTC®4151 is a high side power monitor that operates over a wide voltage range of 7V to 80V. In default operation mode, the onboard 12-bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I2C interface when polled by a host. The LTC4151 can also perform on-demand measurement in a snapshot mode.

The LTC4151 features a dedicated shutdown pin to reduce power consumption. The LTC4151-1/LTC4151-2 feature split I2C data pins to drive opto-isolators. The data out on the LTC4151-1 is inverted while that on the LTC4151-2 is not.

The LM317AEMP/NOPB is an adjustable 3-terminal positive Voltage Regulator is capable of supplying in excess of 1.5A over a 1.2 to 37V output range. It is exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulations are better than standard fixed regulators. In addition to higher performance than fixed regulators, the LM317AEMP/NOPB series offers full overload protection available only in IC’s. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.
