Lm338 vs lm317

The LM3voltage regulators can provide up to 1. Amperes (A) of output current. Where greater output current is . A large high-power LED array will be difficult to keep cool all by itself. You will essentially need to mount the entire array on a large .

Voltage regulator Circuit. But any ideas on using the same regulators for adjusting output current? V , try using LED with small forward voltage. I do not provide components for.

These are lower-dropout, allegedly faster, and much higher power output. LM3in current-source mode the sense resistor has 1. Internally the device has a bandgap voltage reference which produces a stable reference voltage of V ref= 1.

V followed by a feedback-stabilized amplifier with a relatively high output current capacity. How the adjustment pin is connected determines the output . Specified 7-A Peak Output Current. Adjustable Output Down to 1. Most H (Metal Can), J (Ceramic), and K (Metal Can) Packages from Linear Technology Are Obsolete The LT138A series of adjustable regulators provide 5A output current over an output voltage range of 1. Type LM317L LM317M LM317T LM317K LM338K Maximum load current 1mA 5mA 1. A 5A Output voltage range ( V ) 1. It can produce any amount between 1. My are completely wrong.

LM350K is a very rugged voltage regulator IC with . For applications requiring greater output current, see LM3series (rated up to about 3A) and LM1series (rated up to about 5A) data sheets. Some of the Features of the LM3include: output voltage tolerance, max. V line regulation, max 1A output current, adjustable output down to 1. The output voltage from the LM3and LM3is set using two resistors (Rand R2) with their values chosen according to the following equation: V OUT = 1. Below is our automated voltage calculator for the LM3and LM3regulators.

Simply enter your target.

Supplemental circuits and regulators provide options for pushing LDO output rails to near-zero volts.
