Tiny LDOs generate less than 6.5 µVrms noise at 250 mA full load
STMicroelectronics’ LDLN025 Low-Dropout (LDO) voltage regulators deliver best-in-class noise performance in relation to outputcurrent and footprint, generating less than 6.5µVrms noise at 250mA full load with an outline of just 0.63mm x 0.63mm. To ensure high accuracy and sensitivity the LDLN025 is designed to supply ultra-smooth and stable voltage to precision ICs like ADCs, VCOs, […]
40-V switching regulators take on heads-up displays and other automotive apps
Exar Corporation today announced a new AEC-Q100 qualified family of 40V switching regulators for automotive applications such as infotainment head units and Advanced Driver Assistance Systems (ADAS). The XR76203-Q, XR76205-Q and XR76208-Q are 3A/5A/8A synchronous step-down regulators designed to provide a wide 5.5V to 40V input voltage range and an adjustable output voltage down to […]
Choosing an integration level for power supply functions
Since the first application of the wheel, an element of all practical engineering projects has been the make-or-buy decision. The issue is fractal, arising at every level of the design hierarchy: For any given function, at some level of abstraction, you’ll choose to switch between make and buy. But the decision doesn’t hinge on a […]

Designing adjustable voltage SMPS – I am planning to make an adjustable voltage SMPS. How do I […]
When should I use an LDO versus a switching regulator?
Both switchers and LDOs have their place in power distribution, as each has special attributes. With few exceptions, every electronic circuit needs at least one well-regulated, accurate, stable dc power rail at 12, 5, 3.3 V, or even at 1 V, and many systems need five, ten or more such rails. This power must come […]
40-A power POL regulator features high thermal conduction
Linear Technology Corporation introduces the LTM4636, a 40A step-down µModule switching regulator with 3D construction for quicker heat dissipation and cooler operation in a small package. By stacking its inductor on top of a 16mm x 16mm BGA package, the LTM4636 benefits from the exposed inductor as a heat sink, permitting direct contact with airflow from […]
Step-down switching regulator targets 48-V auto, dual battery transportation, 36-72-V telecom apps
Linear Technology Corporation announces the LT8630, a 600mA, 100V input capable synchronous step-down switching regulator. Synchronous rectification delivers efficiency as high as 93% while Burst Mode® operation keeps quiescent current under 7µA in no-load standby conditions. Its 3V to 100V input voltage range makes it ideal for 48V automotive systems, dual battery transportation, industrial and […]
30-A to 180-A regulator module includes inductor, support components in BGA package
Linear Technology introduces the LTM4647, a 30A step-down µModule (power module) regulator. The LTM4647 includes the inductor, MOSFET, DC/DC controller and supporting components in a 9mm x 15mm x 5.01mm BGA package. The device’s conversion efficiency from 12VIN to 1VOUT at 30A is 87%, when delivering a full 30A continuously without a heat sink or […]
