Part Number Description
Current-Limited
Power Distribution
Switch
TPS2553 This is used for applications where precision current
limiting is required or heavy capacitive loads and short
circuits are encountered.
Regulator TPS61170 This is a monolithic high-voltage boost regulator with
an integrated 1.2 A, 40 V power MOSFET.
Regulator TPS62007 The TPS6200x devices are a family of low-noise
synchronous step-down DC-DC converter that is
ideally suited for systems powered from a one-cell
Li-ion battery or from a two- to three-cell NiCd,
NiMH, or alkaline battery.
Regulator TPS62003
LDO Regulator TPS71501 These are low-dropout (LDO) voltage regulators,
offering the benefits of low noise, low-dropout
voltage, low-power operation, and miniaturized
packages.
LDO Regulator TPS76433
Digital Isolator ISO7241A This is a quad-channel digital isolator with multiple
channel configurations and output enable functions.
Shift Register SN74AHC595 This device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage register.
Switch TS5A3159 This is a single-pole double-throw (SPDT) analog
switch designed to operate from 1.65 V to 5.5 V.
Operational Amplifier OPA171 This is a single-supply, low-noise operational
amplifier.
Operational Amplifier TL062C This JFET operational amplifier features high input
impedance, wide bandwidth, high slew rate, low input
offset, and input bias currents.
ADC ADS8319 This is a 16-bit, 500-kS/s analog-to-digital converter.
DAC DAC8551 This is a small, low-power, voltage output, 16-bit
digital-to-analog converter (DAC).
Reference REF3025 This is a precision, low power, low voltage dropout
voltage reference available in a small SOT23-3.
