TLV1117: tlv1117 alternatives

Yang,

We do not share detailed pricing information on the external forums other than the 1 Ku pricing which is available on TI.com.

Regarding your request, can you provide additional details about the system/application needs here? What package is the customer currently using (SOT-223, TO-252, TO-220, etc)? The traditional 1117 linear regulator comes is many different package options. Can you also clarify what the load current requirements are here (max current, average load current, etc)?

One option to consider here would be the TLV767, which is a recently introduced, next generation 1-A, wide-input voltage linear regulator. The TLV767 delivers many advantages over the traditional, standard linear regulator including:

• Reduced Standby Power:  

• 50 µA I_Q (<10% of previous generation I_Q)

• No minimum load required to achieve proper regulation/stability

• Superior electrical performance:

• 1% output voltage accuracy across line, load, and temp (-40 to 125 C)

• Excellent ripple rejection: 53db PSRR at 100 kHz. 

• Simple, easy-to-use solution:

• Ceramic cap stable with minimal input capacitance. No need for tantalums.

• Foldback current limiting to help enable safe low power circuits

• Reduced inrush current to deliver a controlled, stable startup

• Improved thermals in a compact package (4 mm²):

• θ_JA=77.7°C/W in 2x2 WSON package
