LM337 Linear Voltage Regulators, Texas Instruments


Texas Instruments LM337 adjustable negative voltage regulators offer the current rating of 1.5A and (100 mA on the LM337L) on the output voltage range of –1.2 V to –37 V. The linear voltage regulator requires only two external resistors to adjust the output voltage and a capacitor for frequency compensation.

Output Current: LM317 (1.5 A), LM317L (0.1 A)
Ripple Rejection 77 dB to 80 dB (Typical)


Linear Voltage Regulators, Texas Instruments


A range of fixed and adjustable Linear Voltage regulators from Texas Instruments. The range includes both positive and negative polarity devices with output current ratings from 100mA up to 5A.
